The Spirit of Anti-Christ

Where does the spirit of antichrist dwell? How do Saul and David represent the spirit of antichrist and the Spirit of Christ? How was David a type of Christ? What is the chief end of man? How are we to understand the Glory of God and Who is the Glory of God? Who was it that spoke to Adam and Eve in the garden? How is non-repentance the spirit of antichrist? Why was Saul unable to kill David? Would God ever subject Himself to a depraved man's will in the matter of salvation? What does evil mean?
